I've been asked to weigh on this, I was waiting for discussion to die down so I could take in all the facts before making a statement, but it doesn't look like that's happening any time soon.
Serious sounding statement representing OpenXcom followsDo what you want. We're not taking any sides on this or enforcing any restrictions at this time. OpenXcom waives any responsibility regarding what players do with it. We are fine with you creating OpenXcom-related content (mods, videos, guides, etc) for free, donations or otherwise. We're only required to do anything about content hosted on OpenXcom.org and Mod.io servers if lawyers come knocking. In fact, legally, you could sell OpenXcom for $10 on Steam tomorrow with all your own original content and be in the clear (so long as the code remains open-source).
We only ask that you respect creators' wishes to the best of your abilities when using their content, and we will do the same. Any disputes should preferably be solved privately between the parties and not by us. If you force our hand, you probably won't like it.
Content creators, if you have concerns over how your content is used, attribution, remixing, etc, please be upfront about it. As has been brought up, licenses like
Creative Commons may be useful as they've done most of the work. We can provide advice but we'd rather not be judge, jury and executioner. Don't assume saying nothing means free-for-all, this isn't Google Images. These arguments come up all the time in modding communities, so none of this is new ground. Research and cover your ass if you must.
Personal opinions from SupSuper that may not represent the views of any other OpenXcom contributor followFrom my perspective, Hobbes had an issue with how other modders were using his content, brought it up with them, and eventually settled on a resolution. A bit drastic, but a lot was discussed in private so we're not seeing the whole picture. Nonetheless the issue was resolved, each side's wishes were followed. There was no big public outcry, no schism, no end of modding. And yet, everyone else decided to start sniping from the sidelines, worried about imaginary repercussions and coming to defend their side. "Slippery slope", "Think of the children", etc.
This is not a legal matter. Mods are a grey area. OpenXcom is a grey area. Attribution is not absolution, it's admission. Fair use is a defence for the courts, not a "get out of jail free" card. As it stands, we have mods using everything from copyrighted content, IPs, trademarks, etc. Trying to define what is and isn't "original content" will not go well for you. Any army of lawyers could wipe you off the map. The law is not on your side. Don't bother arguing this.
This is a moral matter. Just because the law is not on your side doesn't mean nobody has any say. In the end we're all operating entirely on "good faith", that's basically how modding works. It doesn't mean we all have the same opinions: "money poisons all", "everything should be shared", "my time is valuable", "for the greater good", etc. I get it, they're controversial topics. But I think the involved parties have already made up their minds, so arguing further is just adding fuel to the fire. Respect everyone's opinions, agree to disagree.
Personally, I do not fear the army of lawyers, or the slippery slope of jerks that are just waiting for the chance to tear modding apart with their stashes of exclusive closed content. That's counterproductive. I don't think there's any inherent benefit in enforcing everything to be under one rule. Content creators can create amazing things whether for free or for a price. Different people have different priorities and produce content differently. Let authors have their say. I don't care for getting credit or a cut of everyone's work. I'd rather OpenXcom be a launching point for every kind of crazy cool idea people have, than just another source of the "license boogeyman". But this is all personal, so I may be proven wrong. Hope not.
